Have had my Blvd for 3 years and about 7K miles. It has had a chronic albeit infrequent problem with getting locked up on restart after being ridden for varying lengths of time. Sometimes seems to have a relationship with very hot weather but not always. At first, I thought it was a battery problem but after experiencing it about a dozen times over three years, I have decided it is more of a compression lock problem. By that I mean that the battery tries to turn it over quite well but it "immediately" hits a strong compression stroke that it can't overcome. My theory is that there are times that it just happens to stop at the point of the 4 cycle stroke where some compression has started to build. When very hot, this trapped air might even gain in compression while first sitting and it just doesn't have the power in the battery and starter to overcome it. The fix, I have discovered, is to simply let the bike sit for about 15 to 30 minutes over which time I suspect the compression bleeds down and then, usually by rapidly engaging the starter repeatedly, it will finally turn over easily and start right up.
Is anyone else having a similar problem or a suggestion for a possible fix?
After several replies re the battery, I will add that I have already installed a brand new battery as a precaution, ride on a regular basis which keeps it charged well and when the problem occurs, even using jumper cables from a known more powerful battery does not get it to turn over so I don't think the battery is the problem. I will check the cables and starter. Anyone know a way to check the torque of the starter or does one just have to put a new one on if all else checks out OK?
